Title: Improvements in and relating to the locking and releasing mechanism of automatic vending machines
Filed: 1929-03-22
Abstract: 326,036. Wistoft, S. March 22, 1929. Coin action, mechanicalconnection; testing coins. -A coin-freed mechanism for locking and releasing automatic vending machines of the kind operable only by coins having a flange comprises a slidable locking bar 2 which on the opening member of the machine being operated is moved upwardly, the movement being arrested by the beak 37 of a pivoted pawl 34 engaging a tooth 3 on the bar unless a flanged coin has been inserted in the machine. ' A coin on insertion falls into a pocket formed by a U-shaped member 46 and rests on an arm 50 of a lever 50, 51. The member 46 and coin abutments 43 are carried on a recessed plate 39 attached to the pawl 34. The pawl 34 is connected by a spring 32 to a pivoted arm 14 carrying a slotted plate 20 on which are mounted two feelers 24. The left hand ends of the feelers are normally held by springs 28 in contact with fixed stops 27 so that their beaks 25 are sufficiently apart to allow the passage of a coin. The arm 14 also carries a pin 18 extending into a slot 9 - - 12 in a plate 8 secured to the bar 2. This slot is so shaped that on the bar 2 being moved upwardly the arm 14 is moved to the right, thereby allowing the springs 28 to move the feelers 24 so that their beaks 25 pass through gaps 48 in the member 46 and engage the inserted coin. During further movement of the arm 14 the beaks strike the flange of the coin and cause the coin by engaging the abutments 43 to move the pawl 34 to the right, thereby allowing the passage of the tooth 3 past the beak 37. As the bar 2 is moved farther upwards the beak 37 slides on the smooth part of the edge of the bar and the engagement of the pin 18 with the inclined part 11 of the slot causes the arm 14 to be moved to the left until on the feelers 24 engaging with the stops 27 the coin is released. During the movement of the bar a spring 53 holds a pin 52 on the lever arm 51 in engagement with bevelled surfaces 6, 5 on the arm 2 and the arm 51 is moved first to the right and then to the left so that the released coin drops through the recesses 21, 40 in the plates 20, 39 into a space between two plates 55 and will fall to the right of the lever arm 50 which guides it into a coin box. If an unflanged coin or disc has been inserted in the machine the beaks of the feelers 24 slide off the coin during the movement of the arm 14 to the right caused by the initial movement of the bar 2 and the locking pawl therefore remains in operative position to prevent further upward movement of the bar 2. During the initial movement of the bar 2 the arm 50 is moved to the right so that the released coin will fall between the plates 55 on the left of the arm 50 and will be guided out of the machine.

Title: Improvements in military land mines
IPC: F42C11/00
Filed: 1940-05-29
Abstract: 541,624. Military land mines. CROWLEY, J. F. May 29, 1940, No. 9441. [Class 9 (ii)] An explosive land mine is constructed so that it is armed by the passage of one or more vehicles over or near it and is only exploded by the passage of a subsequent vehicle. In use the mines are laid in successive rows of which only the innermost row is set to explode on the first contact, the other rows being set to permit the passage of one or more vehicles, according to their position, before they can be exploded. The arming may be effected by the action of the weight of the passing vehicle or by acoustic or other dynamic waves generated by it. Fig. 1, shows a mine having a movable cover 1 carrying striking pins 12 co-operating with percussion caps 13. Initially a cam 8 on a shaft 5 co-operates with a stop 9 to prevent the striking pins from reaching the percussion caps when the cover is depressed, but the cam is turned step by step at each depression by a pawl 3 engaging a ratchet wheel 4 on the shaft 5 until it no longer obstructs the stop 9. The number of steps required is determined by the initial setting of the cam which is effected by turning the shaft 5 from outside the casing. In another form a diaphragm responsive to sound waves completes an electric circuit through a solenoid to move the cam one step, a delay action relay preventing a second energization until after the lapse of a suitable interval. As an alternative a mercury switch responsive to earth tremors may energize the solenoid. According to the Provisional Specification the magnetic mass of the tank may act upon a circuit in the mine to effect the arming operation.

Title: Improvements in or relating to television systems
Inventor: ROE GRAHAM DUDLEY
IPC: H04N5/275
Filed: 1969-02-21
Abstract: 1,235,831. Television. BRITISH BROADCASTING CORP. 22 Jan., 1970 [21 Feb., 1969], No. 9586/69. Heading H4F. In a television fade-over and special effects arrangement in which parts of two television pictures are reproduced on separate areas of a display screen in a pattern, the relative amounts of the two pictures are controlled so that their linear dimensions in the pattern are directly proportional to a control voltage. As shown, Fig. 2, a pattern waveform generator 12 is connected to a pulse-forming circuit 14 which generates at its output 16 a waveform which has first and second levels when the magnitude of the pattern waveform is respectively greater than and less than the magnitude of a D.C. signal applied to input 15. A changeover switch (not shown) connected to two television signal sources is controlled by the output signal at terminal 16. This output signal is also integrated and the resulting D.C. signal compared with the variable control voltage, for changing the relative amounts of the two signals displayed, in a differential comparator 20, the output of which comprises the D.C. signal which is applied to circuit 14. Integrator 18 and comparator 20 effectively constitute a feedback loop around circuit 14 the effect of which is to cause the magnitude of the integrator output to equal the control voltage from source 22, hence, since the integrator output voltage is dependent upon the pulse-output waveform of circuit 14 the relative times at which the output pulse waveform is at its first and second levels is directly dependent upon the magnitude of the signal from the source 22. The pattern generator waveform may comprise a sawtooth, triangular or parabolic (see later) waveform having the same period as the line timebase waveform of the television system. In Fig. 3, in which a more complex pattern is produced a second pattern generator 24 is connected, as shown, to a second pulse-forming circuit, this generator being arranged to generate cyclically a pattern waveform having the same period as the frame (instead of the line) timebase waveform of the television system. The ouputs at terminals 16 and 28 are fed via an OR circuit to the above mentioned switch. In operation if generators 12 and 24 generate triangular pattern waveforms, and the outputs 16 and 28 are combined before application to the switch, part of one television picture appears as a rectangle in the centre of the screen, the size of which is controlled by the D.C. signal from source 22. In an alternative arrangement output terminal 16 is not used, the output from generator 12 being added to the output of generator 24. With this arrangement with triangular pattern waveforms part of one television signal will appear as a diamond in the centre of the screen. If parabolic waveforms are used a circle is produced, and even with these non- linear (parabolic) waveforms the linear diversions of the pattern are directly projectional to the control voltage from source 22.
